Missing AVCaptureConnection.VideoRotationAngle

[dartasen]

Apple platform

iOS

Framework version

net9.0-*

Affected platform version

.NET 9.0.101

Description

AVCaptureConnection.VideoOrientation seems to be obsolete on iOS 17+, telling us to use AVCaptureConnection.VideoRotationAngle instead.

However it seems that currently AVCaptureConnection.VideoRotationAngle is readonly

Steps to Reproduce

n/a

Did you find any workaround?

No response

Relevant log output

var videoRotationAngle: CGFloat { get set }

I can confirm this, and a fix is in progress.

Do you need a workaround in the meantime?

@rolfbjarne Awesome, thank's

If there's one available i'll happily take it, otherwise i'll wait for a service release

Something like this should work:

using System.Runtime.InteropServices;
using ObjCRuntime;

[DllImport (Constants.ObjectiveCLibrary)]
static extern void objc_msgSend (IntPtr handle, IntPtr selector, nfloat value);

public static void SetOrientationAngle (this AVCaptureConnection connection, nfloat orientationAngle)
{
	objc_msgSend (connection.Handle, Selector.GetHandle ("setVideoRotationAngle:"), orientationAngle);
}

// ...

previewLayer.Connection.SetOrientationAngle (orientationAngle);
